The Sixteenth fought well during the Third and Fourth Succession Wars, but was relegated to garrison duty in 3033 after offending the Warlord of Galedon. During the Ronin Wars, the unit's commander threatened to side with the rebellious Warlord of Dieron unless his unit was given a better assignment. This action hurt the unit's reputation and priority listing for new equipment. The commanding officer who threatened to side with the Ronin forces was relieved of command.[1]

The Sixteenth was assigned to assault Thestria and remove the AFFS forces that were on the world. The Dioscuri's Castor Regiment faced the Sixteenth and engaged in a bloody series of battles that inflicted heavy losses on the Regulars.[2] The 1st Proserpina Hussars arrived to support the Regulars, and the CO of the Hussars offered the mercenaries a chance to withdraw. Outraged by this, Tai-sa Leonard Kobayashi (a strong traditionalist) ordered his Sixteenth Regulars to attack the mercenaries. The Dioscuri troops destroyed the Regulars battalion while the Proserpina Hussars just watched. The mercenaries then took as much salvage from the wreck of the Regulars as they could and left the world. Tai-sa Kobayashi and several other high ranking officers committed seppuku to atone for their poor performance.[3]

The unit's new commander worked hard to improve the unit's reputation which had suffered because of their commander's actions during the Ronin Wars and their performance in the War of 3039. For the next thirty years, the Sixteenth was used only as a garrison force, seeing little combat.[1]

Based on Senorbi during the Jihad the Sixteenth Galedon Regulars took heavy losses from Black Dragon Society sympathizers and yakuza forces. Between the terror attacks of the yakuza and the influence of the Black Dragons, the Sixteenth found more than half it's equipment and warriors destroyed. At the close of the Jihad they remained on Senorbi.[5]

The Sixteenth responded to the yakuza attacks by eliminating most of the yakuza on Senorbi. The Sixteenth spent the rest of the Jihad defending the Combine's border with the Outworlds Alliance as a counter to adventurism by Clan Snow Raven. The Ravens never jumped the border however. Later, the DCMS High Command ordered the Sixteenth to take Budingen from the Snow Ravens after the Clan took that world. The Sixteenth wasn't able to do so, but did inflict heavy losses on the Gamma Galaxy defenders.[6]

During the 3130s, the unit would remain stationed on the Raven Alliance border, which it would focus on specializing it's tactics to cope with Clan Snow Raven raids and possible attacks of their own against them. Notably, Regiment would be enhanced with three additional conventional forces. These would in include a Combat Vehicle Regiment, named ,Nest Reavers, focus around assault tanks and fast hovercraft. The unit's infantry regiment, the 252nd would enhanced with Assault Battle Armor. Regular's aerospace attachment, Raven Hunters, is focus their specialization on ground assault, while notably less skilled engaging enemies in space.[7]

In 3144 the Sixteenth Galedon attacked McGehee as part of the Draconis Combine's advance into the Federated Suns. There they faced the 4th Robinson Strikers. Regulars grinded the Stryker's positions and over took number of command outputs. However, the specialized Battle Armor elements from Stryker's 302nd Amphibious Platoon would end up conducting a daring raid while FedSuns prisoners would being transported by watercraft. The Regular's would ultimately force the Strykers to withdraw from the planet, however take heavy casualties in the process.[8][9] They were also part of the attack on Rowe.[10] During the assault on Rowe, their assault company was filled with TenshiOmniMechs. They would conduct campaign that would lead to destruction of the Rowe's militia and ultimately level it's capital of Kirstie.[11][12]

The Sixteenth relies on reconnaissance from its detachment of VTOL craft. This aids them in the urban combat that is their specialty, as VTOLs perform admirably in such terrain, while aerospace fighters do not fight as efficiently in it.[1]
